Q: What about someone who believes God exists wholly apart from evidence, say, on the basis of their religious experience, like William Alston and William Lane Craig argue, who claim the existence of God can be immediately known and experienced wholly apart from objective evidence?

A: I'd say such a claim itself is not based on objective evidence, which is the only reality check we can have against false subjective claims. For the evidence of subjective religious experiences is trumped by the objective evidence that the Christian god, the one they claim to have subjectively experienced, does not exist. That kind of objective evidence abounds. Objective evidence is also the reality check for all people of faith who claim similar subjective experiences are veridical. People of faith who reverse this by claiming subjective religious experiences trump all objective evidence are not thinking like adults, so they must go to the children's table. They are deluded. They are Epistemological Solipsists.
